“…This type of amplification offers many advantages in comparison to other conventional amplifiers, such as presenting low noise figures, and allowing a broad and flexible gain bandwidth to be achieved using relatively simple structures [2]. Moreover, such gain bandwidth shaping flexibility in Raman amplifiers have attracted a lot of attention, since simply by using an optimized combination of different pump lasers, regarding its wavelength and optical power, the overlapping of the Raman gain sprectrums related with each pump could yield the construction of wide band flat-gain amplifiers, encompassing optical telecommunication systems to operate in the full extent from the S-to the L-band [3], [4].…”

This paper presents a numerical study and the optimization of very short discrete multi-pump Raman amplifiers using Tellurite-based optical fibers. While most studies about discrete Raman amplifiers usually focus on cases where hundreds of meters of fiber are used, here we consider a multi-pumped Raman amplifier setup with extremely short dimensions, in which the length of the gain media was varied from 2.5 to 30 meters. The optimization process was developed over an broad amplification band from 1520 to 1600 nm, considering a maximum acceptable ripple of 3 dB, and using 2, 3 and 4 pumps with individual powers always below 2.5 W. The results show that it is possible to achieve net gains as high as 10 dB for gain media around 20 meters, and close to 15 dB for 30 meters. These high gains highlight the fact that Tellurite-based optical fibers can be used for the construction of very short and compact broadband amplifiers using just a few pump lasers with modest optical powers.
